21/41
Step-by-step explanation:
Find the total number of students
6+7+2+3+6+8+4+5=41
Then find the students that do not study chemistry
6+7+2+5 = 20
P( not study chemistry) = do not study chem)/total
=21/41
20 because when you do it that way when it is behind the decimal the numbers are always the opposite thousand hundred tens ones . tens hundreds thousands
City C (42 and 66 are the two modes they are the most frequent numbers both appearing 3 times)
Trick question — it’s a right triangle. Here’s why:

0.33% because you just divide both of them together, I will show my work on paper, it will take a second
